' KNIFE Eon FRUIT-Pri**rma EACHINESQ.

T o all 'whom t may concern.' t

Be it known that I, GEORGE R. PARANTEAU, a citizen of the United States of America,

and resident of Ventura, in the county of` Ventura and State of California, have in# vented certain new and useful vImprovements in Knives for Fruit-Fitting Machines, of which the4 following is a specification.

This invention relates to pitting machines and has for its object'the provision of novel means for slitting fruit and for presenting pit resisting portions operative to arrest the pit Vand dislodge it from the fruit while the fruitis being carried past the knife. While this invention is primarily t intended to beused as a part ofv fruity pitting machines similar to those embodied inr my application for patent filed Sept. 21, 1920, Serial Number 411,841, it is capable of use separate therefrom and as an accessory to other fruit pitting or treating .'machinery, and I do not therefore wish tobe limited with respect to its installation or applica` tion. Y

It is an ob ect 'of the invention, therefore,

to produce a knife of such configuration and e characteristic as to have'a cuttingr edge engage fruit as it is ascending or carried by a wheel or other conveyer yfor the purpose of slitting --the fruit circumferentially and to then present pit engagin portions which are contacted during the. urther movement of the fruit so that the pits are dislodged from the fruit without liability oflth'e pit` adhering to one orthe other sections of the fruit being carried. f

It has been found in practice that a device made in accordance with theinvention is more satisfactory and more positive in its action than those of knownconstruction and it is comparatively simple in form and inexensive. With the foregoing and other objects. in view, the invention consists in the details of construction, and in the arrangement and combination of parts vto be hereinafter morel fully set forth and claimed. 7

In'describing the invention in detail, ref-A erence will be had to the accompanying drawings forming part vof this application knives for fruit y tion, t .Y and terminatin in a dual blade having a space between t e cutting edges thereof l x .vSppeccation of Letters Patent. f Patented Ot, 4:, 192i Application niednarh 16,1921. seriainaasaia. v

Fi line 3 3 of Fig. 1. Y

I have shown the invention as applied to a bed plate 5 and heldin place thereon byk brackets 6 between which the shank 7 :of the knife 8 is secured by Vfastenings 9 such asv bolts.

The cutting or operating portion of the knife may be said to consist of an approximately horizontally' movement of a circular carrier Vsuch as is shown in the aforesaid application, The

t disposed blade 10 which, however, is slightly curved to conform to the g. 3 illustrates a sectional view on the Y approximately horizontally disposed portion 0f the blade has a single cutting edge which single portion the line 11. From ythe line 11 to a point approximately the line 12, the knife hasa double cutting edge 13 and v14 in such spaced relation to eachv other-as to cause a spreading of the previously been cutby the single blade, and owing to the fact that the two cutting edges gradually diverge from the single cuttingv edge, they perform what might be termed a stripping action in severing the fruit from the pit, vwhile at the same time the pit is caused to bearV against two points of resistance comprising the cutting edges 13 and 14, a condition which prevents any wabbling two. halves of fruit 'which had terminates at approximately l f of the pit or any tendency to adhere to one half of the fruit rather than to theother half thereof, and in fact, the knife is so effective in this regard that the pit is dislodged from the fruit as the fruit carried by the conveyer.
